In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements with normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of June 30, 2021, and the Company’s consolidated results of operations, change of convertible and redeemable convertible preferred stock and stockholders’ deficit, and cash flows for the three and six months ended June 30, 2021 and 2020. The results for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021, or any other future interim or annual period. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, income tax uncertainties, stock-based compensation cost, fair value measurement of warrants, accretion of redeemable stocks, fair value and useful life of intangible assets, as well as in estimates used in applying the revenue recognition policy. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates. Due to the Coronavirus (“COVID-19”) pandemic, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require a material update to its estimates or judgments or an adjustment of the carrying value of its assets or liabilities as of June 30, 2021. While there was not a material impact to the Company’s condensed consolidated financial statements as of and for the three and six months ended June 30, 2021, these estimates may change, as new events occur and additional information is obtained, as well as other factors related to COVID-19 and its variants that could result in material impacts to the Company’s condensed consolidated financial statements in future reporting periods. Restatement of previously consolidated financial statements The Company has restated its previously issued consolidated financial statements as of the year ended December 31, 2020, to amend the underlying assumptions used in its common stock valuation work. See Note 20 to the consolidated financial statements included in the Company’s Prospectus for further information. Concentration of Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, restricted cash and trade receivables. The majority of the Company’s and its subsidiaries’ cash, and cash equivalents and restricted cash are invested with major banks in the United States, Israel, and the United Kingdom. Such investments in the United States may be in excess of insured limits and they are not insured in other jurisdictions. In general, these investments may be redeemed upon demand and therefore bear minimal risk. The Company’s trade receivables are geographically dispersed and derived from sales to customers mainly in the United States, Europe, and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation, and account monitoring procedures. Major customer data as a percentage of total revenues: The following table sets forth a customer that represented 10% or more of the Company’s total revenue in each of the periods set forth below: Three months ended June 30, Six months ended June 30, 2021 2020 2021 2020 (unaudited) Customer A (M&T) * % 12.03 % * % 12.90 % Customer B (EE&T) * % * % $ 10.01 % * % *) Represents an amount that is lower than 10% of the Company’s total revenue. Significant Accounting Policies and Estimates There were no material changes to the significant accounting policies and estimates during the six months ended June 30, 2021. Recently Adopted Accounting Pronouncements As an “emerging growth company”, the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software. The new standard requires capitalized costs to be amortized on a straight-line basis generally over the term of the arrangement, and the financial statement presentation for these capitalized costs would be the same as that of the fees related to the hosting arrangements. The Company adopted this guidance prospectively on January 1, 2021, and the adoption did not have a material impact on its condensed consolidated financial statements. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases, which would require lessees to put all leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. In June 2020, the FASB issued ASU No. 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which defers the effective date of ASU 2016-02 for non-public entities to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The guidance will be effective for the Company beginning January 1, 2022, and interim periods in fiscal years beginning January 1, 2023. The Company is currently evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance will be effective for the Company beginning January 1, 2023, and interim periods therein. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-13 will have on its consolidated financial statements and related disclosures. In January 2017, the FASB issued Accounting Standards Update No. 2017-04 (ASU 2017-04) "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2021; early adoption is permitted. The Company does not expect that ASU 2017-04 will have an impact on its consolidated financial statements and related disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing a variety of exceptions within the framework of ASC 740. These exceptions include the exception to the incremental approach for intra-period tax allocation in the event of a loss from continuing operations and income or a gain from other items (such as other comprehensive income), and the exception to using general methodology for the interim period tax accounting for year-to-date losses that exceed anticipated losses. The guidance will be effective for the Company beginning January 1, 2022, and interim periods in fiscal years beginning January 1, 2023. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2019-12 will have on its consolidated financial statements and related disclosures.

FAIR VALUE MEASUREMENT

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	NOTE 4: FAIR VALUE MEASUREMENT FASB ASC No. 820, “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value. Fair value is an exit price, representing the amount that would be received for selling an asset or paid for the transfer of a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value: Level I - Unadjusted quoted prices in active markets that are accessible on the measurement date for identical, unrestricted assets or liabilities; Level II - Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level III - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). The table below sets forth the Company’s assets and liabilities measured at fair value by level within the fair value hierarchy. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. June 30, 2021 Level 1 Level 2 Level 3 Total Warrants to purchase preferred and common stock $ - $ - $ 53,855 $ 53,855 December 31, 2020 (As restated) Level 1 Level 2 Level 3 Total Warrants to purchase preferred and common stock $ - $ - $ 56,780 $ 56,780 The Company measures the warrants at fair value by applying the option-pricing model in each reporting period until they are exercised or expired, with changes in fair values being recognized in the Company's consolidated statement of operations as financial income or expenses. In estimating the warrants' fair value, the Company used the following assumptions: June 30, 2021 December 31, 2020 (unaudited) Volatility 40.78 % 65.23 % Risk-free interest rate 0.05 % 0.09 % Dividend yield - - Expected life (years) 0.164 0.405 1. Dividend yield - was based on the fact that the Company has not paid dividends to its stockholders in the past and does not expect to pay dividends to its stockholders in the foreseeable future. 2. Expected volatility - was calculated based on actual historical stock price movements of companies in the same industry over the term that is equivalent to the expected term of the option. 3. Risk-free interest - based on yield rate of non-index linked U.S. Federal Reserve treasury stock. 4. Expected term - the expected term was based on the expected maturity date of the warrants. Fair value measurement using significant unobservable inputs (Level 3): June 30, 2021 December 31, 2020 (as restated) (unaudited) Balance at January 1 $ 56,780 $ 17,111 Issuance of warrants - 1,221 Reclassification of warrant to common stocks to equity - (3,057 ) Reclassification of warrant to common stocks to mezzanine equity (1,149 ) - Change in fair value of warrants (1,776 ) 41,505 Balance at the end of the period $ 53,855 $ 56,780 Upon the closing of the Company’s IPO, after the balance sheet date, warrants to purchase preferred and common stock were converted into 7,067,699 shares of common stock. Prior the conversion, the Company estimated the fair value of the warrants. The valuation resulted in an expense of $16,822 (See Note 15 Subsequent Events for further information related to the IPO).

Income Taxes Paid, Net [Abstract]
PROVISION FOR INCOME TAXES	NOTE 7: PROVISION FOR INCOME TAXES The Company recognized an income tax expense of $1,446 and $554 for the three months ended June 30, 2021 and 2020, respectively, and $3,252 and $1,906 for the six months ended June 30, 2021 and 2020, respectively. The tax expense for these periods was primarily attributable to pre-tax foreign earnings. The Company’s effective tax rates of (114)% and (5)% for the three months ended June 30, 2021 and 2020, respectively, and of (22)% and (14)%, for the six months ended June 30, 2021 and 2020, respectively, differ from the U.S. statutory tax rate primarily due to U.S. losses for which there is no benefit and the tax rate differences between the United States and foreign countries. The Company has a full valuation allowance on its deferred tax assets. As a result, consistent with the prior year, the Company does not record a tax benefit on its losses because it is more likely than not that the benefit will not be realized. On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), as a response to the economic uncertainty resulting from the global COVID-19 pandemic. The CARES Act did not have a material impact on the Company’s condensed consolidated financial statements for the three months ended June 30, 2021 and 2020, and for the six months ended June 30, 2021 and 2020. The Company continues to monitor any effects that may result from the CARES Act.

Segment Reporting [Abstract]
REPORTABLE SEGMENTS	NOTE 10: REPORTABLE SEGMENTS a. Reportable segments: ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker (“CODM”) is its Chief Executive Officer. The Company’s CODM does not regularly review asset information by segments and, therefore, the Company does not report asset information by segment. The Company organizes its operations in two segments: Enterprise, Education, and Technology (“EE&T”) and Media and Telecom (“M&T”). These segments share a common underlying platform consisting of the Company’s API-based architecture, as well as unified product development, operations, and administrative resources. EE&T includes revenues from all of the Company’s products, industry solutions for education customers, and Media Services (except for media and telecom customers), as well as associated professional services for those offerings.

LONG-TERM LOAN	NOTE 11: LONG-TERM LOAN In January 2021, the Company refinanced all amounts outstanding under the existing loan agreements as of December 31, 2020, terminated all outstanding commitments, and entered into a new credit agreement (the “Credit Agreement”) with an existing lender, which provides for a new senior secured term loan facility in the aggregate principal amount of $40,000 (the “Term Loan Facility”) and a new senior secured revolving credit facility in the aggregate principal amount of $10,000 (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Credit Facilities”). In June 2021, the Company entered into an amendment to the Credit Agreement (the “First Amendment”). Pursuant to the First Amendment, the Company borrowed an additional aggregate principal amount of $12,500. Borrowings under the Credit Facilities are subject to interest, determined as follows: (a) Eurodollar loans accrue interest at a rate per annum equal to the Eurodollar rate plus a margin of 3.50% (the Eurodollar rate is calculated based on the applicable LIBOR for U.S. dollar deposits, subject to a 1.00% floor, divided by 1.00 minus the maximum effective reserve percentage for Eurocurrency funding), and (b) Alternate Base Rate (“ABR”) loans accrue interest at a rate per annum equal to the ABR plus a margin of 2.50% (ABR is equal to the highest of (i) the prime rate and (ii) the Federal Funds Effective Rate plus 0.50%, subject to a 2.00% floor). The Term Loan Facility is payable in consecutive quarterly installments on the last day of each fiscal quarter in an amount equal to (i) $250 for installments payable on April 1, 2021, through December 31, 2021, (ii) $750 for installments payable on March 31, 2022 through December 31, 2022, and (iii) $1,500 for installments payable on and after March 31, 2023. The remaining unpaid balance on the Term Loan Facility is due and payable on January 14, 2024, together with accrued and unpaid interest on the principal amount to be paid to, but excluding, the payment date. Borrowings under the Revolving Credit Facility do not amortize and are due and payable on January 14, 2024. Amounts outstanding under the Credit Facilities may be voluntarily prepaid at any time and from time to time, in whole or in part, without premium or penalty. As of June 30, 2021, the total future principal payments related to Credit Facilities are as follows: Remaining 2021 $ 500 2022 3,000 2023 6,000 2024 52,500 $ 62,000

On February 3, 2021, SVB Financial Group (“SVB”) converted a Warrant to Purchase Stock issued on February 3, 2011 (the “Series C Warrant”) into shares of the Company’s Series C Convertible Preferred Stock pursuant to the cashless conversion mechanism described in the Series C Warrant. The conversion was exercised for all 31,414 shares covered by the Series C Warrant and resulted in the net issuance of 27,011 shares of the Company’s Series C Convertible Preferred Stock. Pursuant to the terms of the Series C Warrant, the number of net shares issued was determined by dividing (a) the aggregate fair market value of the shares otherwise issuable upon exercise of the Series C Warrant minus the aggregate exercise price of such shares by (b) the fair market value of one share of the Company’s Series C Convertible Preferred Stock. 2. Upon the closing of the Company’s IPO, after the balance sheet date, all outstanding shares of its convertible and redeemable convertible preferred stock automatically converted into 76,262,947 shares of common Stock (see Note 15 Subsequent Events for further information related to the IPO). b. Receivables on Account of Stock: In May 2015, the Company entered into loan agreements with certain of its executive employees for the purpose of exercising vested options to purchase the Company’s common stock (the “Employee Loan Agreements”). In February 2021, the Employee Loan Agreements were amended such that the loans would be automatically forgiven and deemed to have been repaid in full immediately prior to the public filing by the Company of a registration statement under the Securities Act of 1933, as amended. In March 2021, the loans were fully forgiven. Following the forgiveness of the loans, the Company recorded an expense for the six months ended June 30, 2021, in the amount of $1,724 included in other operating expenses in the consolidated statement of operations. The amount includes the tax gross-up expense that will be paid by the Company following the loan forgiveness. c. Stock option plans: Under the Company's 2007 U.S. and Israeli Stock Option Plans ("the 2007 Plans"), options may be granted to officers, directors, employees, advisors and consultants of the Company or its subsidiaries. In 2017, the Company adopted a new equity incentive plan, the "2017 Equity Incentive Plan" (the "2017 Plan" and together with the 2007 Plans, the "Plans"), and extended the term of the 2007 Israeli Stock Option Plan and the term of the options already granted thereunder for an additional ten-year period. In 2017, the Company adopted a new equity incentive plan, the "2017 Equity Incentive Plan" (the "2017 Plan" and together with the 2007 Plans, the "Plans"), and extended the term of the 2007 Israeli Stock Option Plan and the term of the options already granted thereunder for an additional ten-year period. Pursuant to the Plans, the Company reserved 45,482,679 shares of common stock for issuance. Following the adoption of a new option policy, the Company has reserved an additional 18,106,866 shares of common stock. As of June 30, 2021 and December 31, 2020, an aggregate of 190,989 and 24,610 shares of common stock of the Company were still available for future grants under the 2017 Plan. Each option granted under the Plans is exercisable until the earlier of ten years (or 20 years if granted under the 2007 Israeli Stock Option Plan) from the date of the grant of the option. The options vest primarily over a four-year period. Any options that are forfeited or not exercised before expiration become available for future grants. Effective upon the effectiveness of the registration statement for the IPO, the Company adopted the 2021 Incentive Award Plan (the “2021 Plan”), pursuant to which it may grant cash and equity incentive awards to officers, directors, employees, advisors, and consultants of the Company. The Company has reserved 8,500,000 shares of common stock for issuance under the 2021 Plan. A summary of the Company’s stock option activity with respect to options granted under the Plans is as follows: Number of Options Weighted Average exercise price Weighted remaining contractual term (years) Aggregate Outstanding as of December 31, 2020 31,981,404 $ 3.86 7.72 $ 22,134 Granted - - Exercised (326,340 ) 0.87 12,354 Forfeited (166,381 ) 3.62 Outstanding as of June 30, 2021 (unaudited) 31,488,683 $ 3.89 7.28 $ 27,625 Exercisable options as of June 30, 2021 16,038,448 $ 1.19 5.39 $ 18,790 The share-based compensation expense by line item in the accompanying consolidated statement of operations is summarized as follows: Three months ended June 30, Six months ended June 30, 2021 2020 2021 2020 (unaudited) Cost of revenues $ 185 $ 94 $ 466 $ 146 Research and development 791 284 1,724 425 Sales and marketing 464 364 1,204 446 General and administrative 2,773 392 5,779 779 Total expenses $ 4,213 $ 1,134 $ 9,173 $ 1,796 d. Stock Split: In March 2021, the Company’s board of directors and the stockholders of the Company approved a four and a half (4.5)-for-one forward stock split of the Company’s common stock, which became effective on March 19, 2021. The par value of each class of capital stock was not adjusted as a result of this forward stock split. All common stock, convertible and redeemable convertible preferred stock, stock options, warrants, and per share information presented within these consolidated financial statements have been adjusted to reflect this forward stock split on a retroactive basis for all periods presented.

SUBSEQUENT EVENTS

SUBSEQUENT EVENTS	6 Months Ended

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 15: SUBSEQUENT EVENTS Initial Public Offering On July 23, 2021, the Company completed its initial public offering (“IPO”), in which the Company issued and sold 15,000,000 shares of its common stock at an offering price of $10.00 per share. On August 6, 2021, the underwriters exercised in full their option to purchase an additional 2,250,000 shares of the Company’s common stock. The Company received net proceeds of $155.4 million after deducting underwriting discounts and commissions of $10.5 million and other issuance costs of $5.0 million. Immediately prior to the closing of the IPO, the Company recognized the following transactions related to the convertible and redeemable convertible preferred stock and to the warrants to purchase preferred and common stock: • The automatic conversion of the convertible and redeemable convertible preferred stock into an aggregate amount of 76,262,947 shares of common stock. • The issuance of 7,067,699 shares of common stock pursuant to the automatic cashless exercise of warrants to purchase preferred and common stock. Prior to the conversion, the Company estimated the fair value of the warrants. As a result of the valuation, the Company recorded an expense of $16,822 which will be reflected in its consolidated statements of operations for the three and nine months ended September 30, 2021, under financial expenses (income), net. In connection with the IPO, the Company amended and restated its Certificate of Incorporation to change the authorized common stock to 1,000,000,000 shares of common stock and 20,000,000 shares of preferred stock, all with a par value of $0.0001 per share. The condensed consolidated financial statements as of June 30, 2021, including share and per share amounts, do not give effect to the IPO and related conversion of the convertible and redeemable convertible preferred stock because the IPO and such conversion were completed subsequent to June 30, 2021. Pursuant to the terms of a certain warrant to purchase common stock (the “Series F Warrant”), and in the case of the Series F redeemable convertible preferred stock, of the Certificate of Incorporation (as in effect immediately prior to the IPO), the Company was required to make certain cash payments to SSIG (Special Situations Investing Group II, LLC, an affiliate of Goldman Sachs & Co. LLC) if the initial public offering price per share at which shares of common stock were sold (the “Actual IPO Price”) was less than the price per share used to calculate the number of shares issuable upon the automatic cashless exercise of the Series F Warrant or the conversion of the Series F convertible and redeemable preferred stock, as the case may be (the “Estimated Price”). Accordingly, because the Actual IPO Price was less than the Estimated Price, the Company was required to make a cash payment to SSIG in the amount of $1.6 million in connection with the closing of the IPO, and it made such payment in July 2021.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of presentation and consolidation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2020 was derived from the audited consolidated financial statements as of that date, but does not include all of the disclosures, including certain notes required by U.S. GAAP on an annual reporting basis. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2020, included in the Company’s final prospectus dated July 22, 2021 (the “Prospectus”) filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended. In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements with normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of June 30, 2021, and the Company’s consolidated results of operations, change of convertible and redeemable convertible preferred stock and stockholders’ deficit, and cash flows for the three and six months ended June 30, 2021 and 2020. The results for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021, or any other future interim or annual period.
Use of estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, income tax uncertainties, stock-based compensation cost, fair value measurement of warrants, accretion of redeemable stocks, fair value and useful life of intangible assets, as well as in estimates used in applying the revenue recognition policy. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates. Due to the Coronavirus (“COVID-19”) pandemic, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require a material update to its estimates or judgments or an adjustment of the carrying value of its assets or liabilities as of June 30, 2021. While there was not a material impact to the Company’s condensed consolidated financial statements as of and for the three and six months ended June 30, 2021, these estimates may change, as new events occur and additional information is obtained, as well as other factors related to COVID-19 and its variants that could result in material impacts to the Company’s condensed consolidated financial statements in future reporting periods. Restatement of previously consolidated financial statements The Company has restated its previously issued consolidated financial statements as of the year ended December 31, 2020, to amend the underlying assumptions used in its common stock valuation work. See Note 20 to the consolidated financial statements included in the Company’s Prospectus for further information.
Concentration of Risks	Concentration of Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, restricted cash and trade receivables. The majority of the Company’s and its subsidiaries’ cash, and cash equivalents and restricted cash are invested with major banks in the United States, Israel, and the United Kingdom. Such investments in the United States may be in excess of insured limits and they are not insured in other jurisdictions. In general, these investments may be redeemed upon demand and therefore bear minimal risk. The Company’s trade receivables are geographically dispersed and derived from sales to customers mainly in the United States, Europe, and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation, and account monitoring procedures. Major customer data as a percentage of total revenues: The following table sets forth a customer that represented 10% or more of the Company’s total revenue in each of the periods set forth below: Three months ended June 30, Six months ended June 30, 2021 2020 2021 2020 (unaudited) Customer A (M&T) * % 12.03 % * % 12.90 % Customer B (EE&T) * % * % $ 10.01 % * % *) Represents an amount that is lower than 10% of the Company’s total revenue.
Significant Accounting Policies and Estimates	Significant Accounting Policies and Estimates There were no material changes to the significant accounting policies and estimates during the six months ended June 30, 2021.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements As an “emerging growth company”, the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software. The new standard requires capitalized costs to be amortized on a straight-line basis generally over the term of the arrangement, and the financial statement presentation for these capitalized costs would be the same as that of the fees related to the hosting arrangements. The Company adopted this guidance prospectively on January 1, 2021, and the adoption did not have a material impact on its condensed consolidated financial statements. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases, which would require lessees to put all leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. In June 2020, the FASB issued ASU No. 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which defers the effective date of ASU 2016-02 for non-public entities to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The guidance will be effective for the Company beginning January 1, 2022, and interim periods in fiscal years beginning January 1, 2023. The Company is currently evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance will be effective for the Company beginning January 1, 2023, and interim periods therein. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-13 will have on its consolidated financial statements and related disclosures. In January 2017, the FASB issued Accounting Standards Update No. 2017-04 (ASU 2017-04) "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2021; early adoption is permitted. The Company does not expect that ASU 2017-04 will have an impact on its consolidated financial statements and related disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing a variety of exceptions within the framework of ASC 740. These exceptions include the exception to the incremental approach for intra-period tax allocation in the event of a loss from continuing operations and income or a gain from other items (such as other comprehensive income), and the exception to using general methodology for the interim period tax accounting for year-to-date losses that exceed anticipated losses. The guidance will be effective for the Company beginning January 1, 2022, and interim periods in fiscal years beginning January 1, 2023. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2019-12 will have on its consolidated financial statements and related disclosures.
